This invention is directed to a carpenter's tool, namely a novelcarpenter's measuring square device.

PRIOR ART

While superficially related prior art was located in a patentabilitysearch in United States Patent Office classification Class 7, subclass164 thereof and Class 33, subclasses 760 and 342 thereof as follows, norelevant art was discovered overcoming prior problems and achievingnovel benefits of the present invention. In each of the below-notedprior art patents, a flat-bottom of a tape extendable from a tapemeasure mounted on a square, extends with the tape's flat bottom"perpendicular" (vertical) relative to the plane in which the bottomsurfaces of the squared-positioned upright and laterally-extendingmembers of the square member, whereby the tape does not lie flat on aboard surface on which the right-angle member's flat bottoms rest.Additionally, the prior art member combinations have no way of measuringup to precisely the straight-edge itself, as contrasted to thestraight-edge other member on which the tape measure is mounted. Suchpatents located were Andrew U.S. Pat. No. Re. 27,496, Burroughs U.S.Pat. No. 1,323,742, Barbee U.S. Pat. No. 3,335,489, Larsen U.S. Pat. No.4,438,538 and Vasile U.S. Pat. No. 4,700,489.

BACKGROUND TO THE INVENTION

Prior to the present invention, it has not been possible to extend atape measure flatly along a surface on which a square is mounted, apartfrom separately measuring with a conventional tape measure flatly placedon the upper flat surface to be marked and subsequently cut, apart fromfirst drawing squaring line by separate use of a carpenter's squareplaced flatly on the same surface.

For prior existing tape measure and carpenter's square combinations asset-forth in the preceding prior art statement, it has heretofore beenimpossible to extend a tape of a tape measure of those devices for theflat lower surface of the tape to be flatly placed on top of the article(board's) flat surface to be measured and/or marked while concurrentlythe square is flatly placed on the same article's flat surface,necessitating separate unrelated use of each of the tape measure and thesquaring device, merely included in the same tool as an aggregation. Incontrast thereto, the present invention is directed to a trueinterrelated combination with interrelated and interdependent functions,for concurrently using both the measure and the carpenter's square fortheir interrelated functions, including also the tape measure havingread-outs of indicial indicative of exact distance from the end of theextended tape to the straight edge being measured from, even though thedistance from the read-out point is not necessarily the same as theexact or correct measured distance indicated by the marker point of thepresent invention. In this background discussion, such is noted in thecontext of being impossible and not contemplated by the prior art, andyet being a needed interrelated function previously requiring separateand cumbersome and time-losing use of different separate tools. As aresult thereof, much additional valuable time was heretofore repeatedlywasted and/or expended, which may now saved or reduced. Also, it was notas easy nor speedy to ascertain exact measurements, certainly not withthe prior art combinations discussed above in the noted patents whichcould easily result in less accurate eventual markings. While thepresent invention achieves the benefit of combining different tools,namely a tape measure and a carpenter's square and the like, thepreceding and following discussion makes it clear and conclusive that inthe present invention the functions of the combination are made integraland interrelated to one-another, achieving new desirable results notheretofore available.

OBJECTS OF THE INVENTION

Accordingly, objects of the present invention include the overcomingand/or avoiding of problems and/or difficulties and/or disadvantages ofthe type(s) discussed above.

Another particular object is to obtain a novel carpenter's tool by whichthe carpenter's square may be concurrently placed face-down with anextending tape measure also place flatly down on the same surface whileaccurately indicating exact measurement to a straight edge of thesquare.

Another object is to achieve leveling as an integral interrelated partof measuring distance from a squared straight edge line, concurrentlywhile the squaring straight edges and measuring tape are concurrently inmeasuring and aligning positions, for accurate read-outs on the levelingdevice.

Another object is to achieve preceding objects together withconcurrently accomodating potential making of measurements from the samemeasured apex-point of the upwardly extending and the horizontallyextending straight-edges.

Another object is to provide a handle structure facilitating stabilizingpositions of both the square and the extended tape of the tape measureand/or the leveling device.

Other objects become apparent from the preceding and followingdisclosure.

BROAD DESCRIPTION

Broadly the invention may be described as a carpenter's measuring squaredevice for facilitating pre-cut measuring and marking wood members,embodying interdependant and interrelated functions of the variouselements of the combination, as follow. There is provided a carpenter'sflat-faced square. The square includes a conventional upwardly-extendingelongated first member having a first flattened underside extendingbetween upper and lower ends thereof in a first plane and having a firstupper side. Likewise, the square includes a conventional laterallyextending elongated second member having a second flattened undersideextending in the first plane with the second member. In the broadembodiment, the second member integrally and immovably and rigidlyextends from the lower end of the first member with the second member'sflattened underside laterally to a lateral position relative to thefirst member. The second member has a second upper side. A tape measureand mechanism for providing and including an extendable and retractabletape thereof. The tape has a lower flattened face and with an oppositeupper face and with a distal extendable end. The tape measure andmechanism thereof provides for alternate extension and retraction alonga lateral first direction. The tape measure structure(s) and mechanismthereof being rigidly and immovably mounted on and integral withat-least one and normally both of the first and second members and thetape thereof is extendable in the first direction in which the tape'slower flattened face when extended is in at-least one of a) the firstplane and b) a second plane substantially parallel with the first plane.The upright first member has a first straight-edge extendingconventionally upwardly linearly as an upright straight-edge extendingin the second direction. The laterally extending second member has asecond straight-edge extending conventionally laterally linearly as ahorizontal straight edge extending laterally in the first direction. Thetape has a first plurality of spaced-apart indicia ranging in the firstdirection on at-least one of the upper lower face(s) of the tape, witheach of the first plurality being positioned to be indicative of itsdistance as measured from the first straight edge of the first member,to the distal extendable end. The tape measure structure(s) andmechanism thereof include(s) a tape guide structure--inclusive of thehousing for storage of the retracted or partially-retracted tape. Thetape guide structure (or preferably tape measure housing thereof) hasmarker structure(s) and mechanism thereof having at least one markerpoint with which any of the first plurality are alignable and matchableone at a time therewith. The one marker point is positioned to beindicative of a actual measured-distance between the distal extendableend and the upright straight edge. Because a proximal portion of thetape is always within the housing structure and/or channel structureconnected therewith, the position of the indicia itself is notnecessarily always the same as the correct above-noted measured distanceindicated by the marker structure(s).

In a first preferred embodiment as an improvement on the above-describedbroad invention, the guide structure includes channel structure forminga closed channel having at least one open end through which the tape isextendable, the open end being connected by continuous through-spaceextending in the first direction and housing the tape. The channelstructure has a window-forming structure forming a window positioned andadapted such that any one of the plurality is outwardly visiblydiscernible through the window when the viewable number is aligned withthe marker point at the window.

In a third preferred embodiment as a further improvement on the secondpreferred embodiment, the inventive combination additionally include(s)an angle indicating structure(s) and mechanism thereof for ascertainingalternate acute angles of any of imaginary linear lines extending froman apex point at which the first and second straight-edges converge.More preferably, the angle indicating structure(s) and mechanism thereofis mounted on at least one of the first and second member to extendacross actue angular space defined therebetween.

In an fourth preferred embodiment as further improvement on the thirdpreferred embodiment, the inventive combination additionally includesleveling structure(s) and mechanism thereof mounted on at-least one ofthe first and second members, for ascertaining extent to which the firstplane does or does not extend along or parallel to either or both of thefirst and second directions.

In a fifth preferred embodiment as a further improvement on the fourthpreferred embodiment, the novel combination additionally includes ahandle structure(s) and mechanism thereof mounted on at-least one of a)the tape measuring structure(s) and mechanism thereof and b) the secondmember, for sturdily and steadily holding the second member and the tapein an extended state onto a surface of an object to be cut, before orduring measuring and marking thereof prior to cutting an object. Morepreferably, the handle or gripping structure is positioned on or abovethe laterally extending second member above-noted.

In a sixth preferred embodiment as a further improvement on the fifthpreferred embodiment, the tape measure structure(s) and mechanismthereof include(s) a tape lock structure(s) and mechanism thereof forintermittently locking and unlocking any of adjustable degrees ofalternate extension and retraction of the tape. The tape lockstructure(s) and mechanism thereof provide(s) for stabilizing the tapeagainst shifting prior to or during measuring and marking thereof priorto cutting an object.

In a seventh preferred embodiment as a further improvement on the sixthpreferred embodiment, the tape measure structure(s) and mechanismthereof is/are mounted on each of the first and second members.

In an eighth preferred embodiment as an improvement on the broadinvention above-noted, the above-noted guide structure includes channelstructure forming a closed channel having the above-described open endconnected by continuous through-space extending in the first directionand housing the tape, with the channel structure and its above-describedwindow-forming structure forming the above-described window for seeingany one of the plurality as outwardly visibly discernible through thewindow when the viewable number is aligned with the marker point at thewindow as set-forth for the above-described third preferred embodiment.

DETAILED DESCRIPTION

Each of FIGS. 1 through 3 illustrate a common preferred embodiment.Accordingly, for the different views thereof, common identical indiciaare utilized. Once an element or feature of an indicia of one isdescribed for one figure, description is not repeated for other figuresexcept in some instances for purposes of improving clarity andunderstanding.

In FIGS. 1 and 3 there can be seen the upwardly-extending or uprightfirst member 4 and in FIGS. 1, 2 and 4 there can be seen the horizontalsecond member 5. The upright first member 4 has a first flattenedunderside (or underface) 6 best viewable in FIG. 3. Viewable in FIGS. 1,3 and 4 is the second flattened underside 7 of the horizontal secondmember. The first member's underside 6 extends between the upper end 8and the lower end 9 thereof. The first member 4 extends along or in animaginary first plane. The first member 4 has an upper side (or top orupper face) 10, best viewable in FIG. 1. Likewise, the second member 5has an upper side (or top or upper face) 11 also illustrated in FIGS. 1and 4. This square being thus-described has its first and second membersrigidly and immovably attached as integral parts of a commonsquare-structure as integral and immovable and rigidly one extending atright angle to the other, sharing a common corner, with the secondmember likewise extending in or along the common plane as the firstmember. Accordingly, in that common plane, the second member extendslaterally as viewable best in FIG. 2, for the bottom or underside 7above described. Mounted on and/or integral with typically the secondmember but also in this embodiment being integral also with the commonend 9 above-described of the first member, is a tape measure structureand mechanism thereof--broadly referred to as structure 12, shown in allof FIGS. 1, 2 and 3. As with any conventional tape measure structure andmechanism, the present tape measure and mecahanism conventionallyincludes a tape housing with its enclosed tape 13 of FIG. 1 andconventional mechanism for extension and retraction, includingconventional springs and release and intermittently locking mechanismsand structures thereof--not constituting a part of the inventive subjectmatter of the present invention and this embodiment thereof, but merelysymbolically illustrating a conventional optional type tape-retractioncrank 14 of FIGS. 1, 2 and 3. The tape 13 (FIGS. 1 and 4) has its lowerface 16 (FIGS. 1 and 4) which is--in its stored retractedstate--viewable through window 15 of FIG. 1 by which that portion of theretracted tape has become inverted, there is viewable the tape's bottomor lower flattened face 16 (FIGS. 1 and 4). The upper face thereof ispartially viewable at the tape's extension-portion distal (extendable)end 17 as upper face 18 of FIGS. 1 and 4. The tape is extendablelaterally in a first direction 19 (FIG. 1), and is retractable from anextended state in an opposite direction until in the position and stateshown in the FIGS. 1 and 2. Along a forward side of the horizontalsecond member is an integrally and rigidly positioned straight-edgehaving (FIGS. 1, 3 and 4) extending as a flange 20 downwardly relativeto and in a downward direction 21 (FIG. 1) perpendicular to each of thefirst and second planes above-described. On the lower face 16 of thetape 13 along a length of the tape are a series of space-apart indicia22 viewable through the above-noted window 15, with the indicia being ofnumerical values in inches and being positioned to be accuratelyindicative of the distance from the distal end 17 to the above-notedfirst straight edge 4a as any particular indicia (or a definite point oflocation between two adjacent indicia 22) is aligned with themarker-line or member 23 fixedly and rigidly mounted in or across or apart of the window 16, as viewable in FIG. 1. The tape distal end 17 hasas a rigidly and fixed part thereof a downwardly extending tape-flange24 adapted to be hooked-over an edge of a board-end (for example) alongthe side which second straight edge is to be aligned when the firstmember is positioned at a predetermined desired distance from theboard-end for a drawing of a squared linear line along the firststraight edge 4a by a carpenter or other worker. The extendable andretractable tape measure structure and mechanism thereof above-notedincludes the retracted-tape housing 25a and the permanentlyextended-tape portion housing 25b (all Figures), both housing portions25a and 25b being conventionally shaped to include housing-space thereinfor the tape and for conventional springs, ratchet and/or the likeconventionally housed in a conventsional tape measure--such mechanismnot being the essence of the present invention, except to the extentthat the housing portions 25a and 25b constitute tape guide structurefor the aligned extension and retraction of the tape in direction 19along the second plane in alignment with the second straight edge.

The angle indicating structure 27 is fixedly and rigidly attached to thefirst and second members primarily as a structural support extendingbetween outer portions of those members, but as an added preferredfeature includes thereon angle indicating marks 28 and accuratelyassociated spaced-apart indicia 29 extending therealong indicative ofacute angles relative to the second straight edge and relative to anglesas measured around apex-point 30 located at the corner of the square,thus making the square adaptable for marking other points at whichlinear lines can be subsequently drawn to the apex point for subsequentcutting or sawing of the lumber or other piece being measured--the angleindicating structure and apex point and other above-described featuresbeing viewable as shown in FIG. 1.

As a further feature of squaring prior to the drawing of a cutting orsawing line along the first straight-edge, it is sometimes of utmostimportance to simulteously ascertain that the lumber surface to bemarked and cut is flatly leveled, to prevent potential uneven andinaccurate cuts that will not properly fit, whereby in a preferredembodiment there is included a fixed and rigidly mounted conventionallevel structure 31 (typically bubble-type) and mechanism thereof forleveling along direction 32, here (in this embodiment) being mounted onthe first member 4 on its upper face 10.

The handle structure 33 and mechanism thereof is fixedly integral andrigid with both of the housing portions 25a and 25b, having a detent orindentation 34 (or a through-space hole) therein sufficiently for andarranged to allow hand-gripping by the carpenter or other worker, asbest viewable in FIG. 2.

The tape retraction handle has a conventional type locking mechnism forpreventing the tape from further extending or retraction, typically suchas a conventional friction brake actuated by pressing downwardly(depressing) the lever/crank 14 to engage friction and/or for locking,and releasing by lifting the lever/crank to disengage friction and/orfor unlocking and releasing the tape.

For the above-described invention, for various dimensions thereof, thereare critical broad ranges beyond which the invention would besubstantially inoperative in so far as diminished benefits ofabove-stated objects. Likewise there are critical narrow ranges that areessential in order to obtain preferred optimal results of the invention.Those ranges are as follow.

The first member broadly ranges in length between about 6 inches andabout 24 inches in length, preferably between about 7 inches and 9inches for the firsts linear edge with linearly-extending ruler andindicia thereof beginning at the apex point that is on the inward sideof the second member's downwardly-extending flange as the second linearedge. Measurement to the outer edge of the second member'sdownwardly-extending flange increases that length measurement by thethickness of the downwardly-extending flange, typically by about 1/16inch. The width of the first member 4 broadly ranges from about one inchto about three inches, the narrow range from about 1.2 inches to abouttwo inches.

The second member ranges from about 6 inches and about 24 inches in itslength, preferably about 7 inches to about 9 inches, as measured fromthe first straight-edge. The width of the second member (not inclusiveof the thickness of the downwardly-extending flange 20) broadly rangesfrom about one inch to about three inches, the narrow range from about1.2 to about two inches.

The thickness of each of the first and second members 4 and 5 broadlyranges from about 1/32 inch to about 1/2 inch, the narrow range fromabout 1/32 inch to about 3/32 inch.

The flange 20 extends downwardly in directions 21 broadly from about 1/8inch to about 3/4 inch, narrowly from about 3/16 inch to about 3/8 inch.

In the use of the above-described inventive combination, a carpentertypically hooks the tape flange 24 over the far end of the piece orboard to be cut, and by use of the handle positions the secondstraight-edge 20 along an elongated edge of the piece top be measured,marked and cut, and still using the gripping-handle, moves the firststraight edge to a distance indicated by the mark alignment seen in thewindow, possibly then ascertaining leveling state of being, andthereafter marking with a pencil along the first straight edge.

It is within the scope and contemplation of this invention to makemodifications/variations and/or substitution of equivalents within theskill of the ordinary artisan.
